Can't read gEQDSK files with multiple new lines at end

[bclyons12]

The latest version of EFIT.jl can't read some gEQDSK files that the old version did. For example: g163303.03170_fix.zip

I get the following output:

julia> gfixed = readg(fixed_geqdsk; set_time=0.0)

ERROR: InvalidStateException: Channel is closed.

This appears to be caused by the fact that this file is missing some of the extra data that is read, and it has multiple new lines at the end. It appears common to files produced by CHEASE. The extra new line causes it not to report eof(f)=true so it tries to read a token in the following lines and fails:

EFIT.jl/src/io.jl

Lines 195 to 199 in d63c58c

	for i ∈ 1:3
	if !eof(f)
	xdum = take!(token)
	end
	end

I'm not sure the best fix for this. Maybe a try-catch?

@orso82 @eldond @lstagner I have a fix but don't have permission to push a new branch here for some reason:

git push --set-upstream origin closed-channel-fix

fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

@bclyons12 unless @lstagner gives you write permission you'd have to fork the repo, commit there and open a PR from your repo to the JuliaFusion one
